10 office security tips & ideas

December 11 2025

While home security is often at the forefront of our mind, if you’re a business owner, office protection is just as important. Enhancing the security of your office building is vital for protecting your employees, assets and data.

That may feel overwhelming, so we’ve gathered together 10 essential tips and ideas for upgrading your office’s security. Consider getting in touch with us, too, if you’re at all concerned about your business’ security setup.

1 - Physical barriers

Sometimes, the most effective methods are the simplest. Making sure your office doors, windows, fences and gates are secure can massively improve your office security. Strengthening the perimeter is an easy step that adds another valuable layer of protection.

Make sure all windows are closed before you leave, and always lock gates and doors before heading home.

2 - Alarms and lighting

Don’t underestimate the value of alarms and security lighting. Alarms offer rapid alerts in the event of a security intrusion, and proper lighting can act as a deterrent for potential intruders. Around one-third (33%) of break-ins occur when it’s dark, so make sure your office is appropriately lit.

By making sure possible hiding places like hallways and stairwells have adequate lighting, you’re reducing the risk of someone using them as cover. They also help reduce any trips or falls because of poor visibility. On the outside of your office, motion-activated lighting can improve visibility at night and discourage burglars, particularly in car parks (if you have one).

3 - Access and entry systems

Electronic access controls are not only a great way to regulate who can enter the building, they also provide you with a full list of who’s in the office at any specific time.

Electronic building entry: only permitted individuals can enter the building with keycards or biometric systems. The possibility of misplaced keys ending up in the wrong hands is decreased with a biometric solution such as fingerprints
Scheduled access: determine access rights according to business hours. This could mean that employees have access to the office until 5 or 6 pm, while cleaners or maintenance can only access the building after-hours

4 - Personnel

Having a trained eye on and near the doors of your office is another way to improve security. You can either employ a security guard who can:

Scope out people trying to enter the building
React efficiently in emergency and dangerous situations
Act as a deterrent for people trying to enter your office unauthorised
Patrol and monitor, look over any CCTV/surveillance systems, and ensure doors, windows and unoccupied rooms in your building are safe

Or, if a security guard feels unnecessary for your office and business, a receptionist might be a better fit. Receptionists can:

Have eyes on the entrance at all times and manage visitors. They oversee visitor check-ins, provide badges, and keep records of everyone who is on the property at a particular time
Receptionists can play a vital role during emergencies by helping enforce protocols, such as guiding people to safety during a fire or medical emergency
Their vigilance can help deter potential intruders and they can be trained to spot suspicious behaviour or people trying to enter when they shouldn’t

5 - CCTV

CCTV is one of the most effective ways to upgrade your office security. You can monitor the premises from a secure location, and the cameras themselves act as a strong visual deterrent.

6 - Ensure you’re protected against fire

While it's an important precaution to take, security isn’t only about preventing break-ins or theft. A comprehensive security system should also include fire and smoke detection. Most commercial/rented offices will provide this, but if yours doesn’t, consider upgrading to a monitored detector that contacts the emergency services for you. Fire alarms are also required by law, and to be serviced on a regular basis.

7 - Emergency plan

Having all the right physical and electronic security measures in place is great, but they are only as effective as the people using them; that's why an up-to-date and practiced emergency plan is crucial. This is about making sure all your staff know exactly what to do when an incident occurs, whether it’s a fire, a break-in or medical emergency. The plan should clearly outline communication channels, evacuation routes and assigned roles.

8 - Policies and procedures

Don't forget the human element of security. Robust policies and procedures are the backbone of a secure office, covering everything from a simple clear desk policy (to protect sensitive documents) to strict guidelines on handling visitor badges and managing IT access. You need to clearly communicate the importance of security to every employee.

By training your team on things like password strength, identifying phishing emails, and the correct lock-up routine, you reinforce all the other measures you’ve put in place and protect your business from the inside out.

9 – Store sensitive material away

Any confidential documents should be securely stored in safes or lockable containers. If an intruder was to break in and take sensitive material with them, you run the risk of a potential data breach.

10 – Protect your money and equipment

If you store cash on site, always ensure this is protected in a safe (an Association of Insurance Surveys-approved one if possible). Consider investing in device locks, too; these are designed to secure equipment to a surface and make any valuable technology much harder to steal.
